In the pinned post that talks about how to get the penn upgrade tokens it lists the requirements for viewing. For GMM streams you only need to watch a half hour you get the token at 15 minutes and then a twitch pack at 30.
Under the creator side it says we get a twitch pack, then a token at an hour, another twitch at 90 minutes and then finally a ZC pack at 2 hours.
I spent 2 hours this morning on pop stranger and all it gave me was the token and the single pack. There was no timers for anything else. I waited till well after 2 hours to claim anything and that's all there was. So if anybody will be watching Creator streams today or the next two times they do it there's no need to stay for 2 hours because you're only going to get stuff in the first half hour. That's too bad I was really looking forward to the ZC pack today
